Thank the gods and you for these healthy horses! Without your dedicated use of PZP and successful partnership with BLM, we would be facing another roundup and sending more Spring Creek Basin mustangs into captivity. I have heard people say PZP won’t work in HMAs that are too large; I’ve heard them say it won’t work in HMAs that are too small. I’ve heard them claim it is irreversible. I’ve also been privileged to observe for myself many healthy herds in several states where PZP is being implemented successfully, and I applaud those women out there working closely with BLM and the Science and Conservation Center to control fertility and keep mares and ranges healthy so that we can continue to experience views like the ones you share with us!
